IPC: G06F1/24
Filed: 1982-05-31
Abstract: PURPOSE:To prevent a malfunction, by increasing a control signal line for propagating an initializing completion signal, and grasping an electrically operable state of each interface in a system. CONSTITUTION:When a trigger signal is inputted to a CPU 11 through signal lines 15, 16 from the outside, a clear signal of prescribed time width is outputted from the CPU 11, and by this signal, initializing completion FFs 112, 122 are reset. Subsequently, when the CPU 11 and an interface 12 ends the initialization, the FFs 112, 122 are set. Subsequently, when the CPU 11 and the interface 12 end their own initialization, they monitor an initializing signal which propagates through an initializing completion signal line 14. In this way, when all the interfaces end the initialization, the initializing completion signal which propagates through the line 14 becomes ''1'', and each interface becomes mutually an electrically operable state.

Title: Zinc alloy for battery electrode
Inventor: NAKAGAWA JUNZO
IPC: C22C18/00
Filed: 1985-05-02
Abstract: PURPOSE:To obtain the titled inexpensive zinc alloy capable of being made low-mercury or nonmercurial and suitable for battery electrodes by providing a composition consisting of specific amounts of Ga, In, Pb and Al and the balance essentially Zn. CONSTITUTION:The zinc alloy for battery electrodes consists of 0.001-0.5% Ga, 0.001-0.5% In, 0.01-0.5% Pb, 0.001-0.1% Al and the balance essentially Zn, which has superior properties even in a low-mercury or nonmercurial state and is still inexpensive owing to the reduction in the additive quantity of expensive Ga by addition of Al. The reasons why the amounts of the above alloy components are limited are as follows: when the amount of Ga is above 0.5%, expensive and yet ineffective for its expensiveness and when below 0.001%, of little effect; when In is below 0.001%, of little effect, and when above 0.5%, more harmful than effective; when Pb is below 0.01%, of little effect, and when above 0.5%, evil effects are produced; and as to Al, it is effective at 0.001% and above but its upper limit is regulated to 0.1% because its effects do not vary with quantity at the higher concentration side.

Title: Bearing device
Inventor: TACHIBANA KOJI
IPC: F16C33/10
Filed: 1986-04-23
Abstract: PURPOSE:To optimize the extent of heat deformation in a pad and improve a bearing characteristic, by detecting the thickness of an oil film with a surface part of the thrust pad supporting a rotor, and controlling a heater at the backside part. CONSTITUTION:With a turning shaft 1 rotated, a loss to be produced in an oil film 6 being formed between this turning shaft 1 and a thrust pad 2 makes temperature on a pad surface surface part go up whereby heat deformation is induced in this pad due to a temperature gradient in the thickness direction. Since it is so judged that the pad deformation is too much if oil film thickness on the pad surface part is small, the detection value of the oil film thickness detector 10 installed in the pad surface part is inputted into a controller 12, accelerating input of the heater installed in a pad backside part. If so, temperature on the pad backside goes up, therefore the temperature gradient in the thickness direction of the pad is relieved so that the pad heat deformation is checked. With this constitution, a bearing characteristic is improved, and its reliability is thus raisable.

Title: Spread spectrum communication data transmission system
Inventor: GOO RORANDO
IPC: H04B1/707
Filed: 1994-04-08
Abstract: PURPOSE:To provide a spread spectrum communication data transmission system which can effectively use the channels for efficient transmission of data. CONSTITUTION:A spread spectrum communication data transmission system transmits the data by a spread spectrum communication system applying the direct spread. In this system, the priority is decided for the transmission terminals based on the degrees of delay that are allowed by the data to be transmitted by these terminals. If no dead channel is available when a transmission terminal requests a spread code of a data transmission channel (Step 2), the transmission of data is inhibited to other transmission terminals of lower priority levels and the priority is assigned to the terminal that requested the channel (Steps 5, 6). Thus the inhibited terminals are kept waiting for the dead channels (Step 7). A transmission channel control station performs the assignment of transmission channels to the transmission terminals to assign the dead channels if available to each requested transmission terminal. If no dead channel is available, the channel control station performs the assignment of channels to the terminals based on the priority.
